Weather tracker: Mediterranean heatwave sparks concern for marine life
The human-induced climate crisis is making marine heatwaves more intense and prolonged, with sea surface temperatures off the coast of Mallorca since late June frequently exceeding 30C (86F).
Portugal's maritime authority said the southern Algarve had experienced a marine heatwave between the 28 June and the 9 July. Temperatures have been significantly higher than the average observed over the past 20 years – with some areas 5C above normal.
This most recent marine heatwave has been the western Mediterranean's most extreme for this time of year. While sea surface temperatures above 30C are not that unusual later in the summer, such conditions are unprecedented in late June.
The impact on marine wildlife and ecosystems from marine heatwaves can be significant. Prolonged exposure can drain the energy from sea creatures to a point where they can no longer survive. There is also evidence that some species go into survival mode and will not reproduce.
Meanwhile, days of torrential rain across South Korea have been responsible for at least four deaths, with two people still unaccounted for.
The country has been pounded by heavy rainfall since Wednesday, prompting the authorities to warn of landslides and flooding. Landslide alerts were raised to the highest level in several regions late last week, including across Chungcheong.
The Ministry of the Interior and Safety said more than 500mm had been recorded in Seosan, South Chungcheong province, since Wednesday.
As of Saturday, almost 3,000 people had not returned to their homes after more than 7,000 were evacuated. More than 600 properties were reported damaged.
Meanwhile, Tropical Storm Wipha has brought heavy rain and strong winds to parts of south-east Asia. The weather system hit parts of the Philippines before passing to the south of Taiwan on Saturday.
Rain lashed Hong Kong on Sunday as Wipha moved southwards before making landfall on the coast of Guangdong province in China. The storm is expected to reach northern Vietnam this week, bringing very heavy rain.
More than 110mm of rain was recorded in three hours in Hong Kong, with up to 100mph (161km/h) gusts. Cathay Pacific cancelled all flights for much of Sunday and elsewhere trees and scaffolding were toppled.

Firefighters struggle to contain wildfires as heatwave sears Turkey and Cyprus
BILECIK, Turkey/OMODHOS, Cyprus, July 24 (Reuters) - Firefighters battled multiple wildfires across Turkey and Cyprus on Thursday that have scorched swathes of land, forced the evacuation of towns and villages and killed 10 firefighters in central Turkey amid a searing Mediterranean heatwave. At least six separate wildfires were burning across Turkey, and Turkish Agriculture and Forestry Minister Ibrahim Yumakli warned that strong winds and blazing heat were creating extremely dangerous conditions. Ten firefighters were killed while battling a fire in the central Eskisehir province, Yumakli said late on Wednesday, adding that 14 others were injured. Fanned by strong winds, the fire later spread to another central province, Afyonkarahisar. In the northwestern province of Bilecik, fires raged for a fourth straight day, as firefighters struggled to contain them. Residents were evacuated from fire-threatened areas of all three Turkish provinces, though some residents were later allowed to return to areas in Bilecik that were declared safe. "They couldn't intervene. There is no decent road, forests are thick and it's rocky. Helicopters don't work at night, and because they don't work, they couldn't intervene," said Cemil Karadag, a resident of the village of Selcik in Bilecik. "It engulfed our village from two or three sides ... It spread very quickly with the effect of the wind, but, thank God, (the centre of) our village wasn't damaged that much." Another fire in the neighbouring province of Karabuk, where the UNESCO World Heritage City of Safranbolu is located, quickly grew and led to 10 villages being evacuated. On the eastern Mediterranean island of Cyprus, firefighters battled for a second day to control a massive wildfire which engulfed mountain villages north of the city of Limassol. Six countries from Spain to Jordan were deploying aid, officials said. Two people were found dead in their car, trapped by the blaze which started on Wednesday. Scores of homes were destroyed as people fled a towering wall of flames overnight. Although the fire's cause was not immediately known, authorities said they would be looking into the possibility of arson. Authorities were struggling to contain flare-ups that were being stoked by strong winds, cranking up water drops by aircraft to prevent it reaching a state forest and before nightfall. "We are facing an unprecedented situation," said government spokesperson Konstantinos Letymbiotis. He said Jordan and Egypt deployed firefighting aircraft on Thursday, while assistance was expected from Spain, Israel, Lebanon and Greece. "When dawn came we saw a catastrophe of biblical proportions," said Kostas Hatzikonstantinou, who struggled to maintain composure as he stood outside his home, hollowed out by the fire which razed his community on Thursday morning. "It's an unspeakable tragedy... Unfortunately, we'll no longer have this paradise that we enjoyed for so many years," he said. The blaze razed an estimated 124 sq km (48 sq miles), officials said, in an area famed for its centuries-old vineyards and wine. Firefighters were struggling to keep it away from the evacuated hamlet of Omodhos, home to a church containing priceless early Christian relics. Ersin Tatar, president of the breakaway Turkish Republic of Northern Cyprus, which is recognised only by Turkey and has been split from the island's south, said his government was ready to assist. Although heatwaves and wildfires are common in the region, their impact on human life along with the scale of destruction have become more pronounced in recent years due to shifting weather patterns.

Entire state of California enduring COLD summer thanks to bizarre weather pattern
The Golden State has been a lot gloomier this summer as California experiences chillier weather and cloudy conditions which experts say is set to stick around. Temperatures in the Bay Area have hovered at an average of 67 degrees, below the average of 71 and making it the coldest summer since 1965. The phenomenon is due to a layer of air near the Pacific Ocean known as the marine layer, which is formed when warm, dry air comes in contact with a cool body of water. In the summer months the warmer weather and cool water create a more dense marine layer, which causes low-hanging clouds that dampen a good beach day. 'The cooler waters off the Baja California coast have lingered through mid-July. The cooler waters have allowed upper-low pressure areas to drift into central California and enhance the marine layer for the Bay area. As a result, the low clouds have been more stubborn than normal this summer,' AccuWeather Senior Meteorologist Chad Merrill told Daily Mail. He noted that the high temperate in San Francisco has been 5 degrees cooler than average and has experienced a higher frequency than normal of overcast skies. 'The onshore flow contributes to the enhanced marine layer and this onshore flow is brought on by a series of upper-lows that have been off the coast and pushed inland through the central part of the state this summer,' Merrill added. This phenomenon is unique to the West Coast because cold water in the Pacific Ocean moves south from the Gulf of Alaska. Water along the eastern Gulf Stream brings warmer tropical water north, meaning the east coast doesn't see the dense marine layer that California does. The marine layer along the east coast reforms almost daily, while along the west coast it can persist for days or weeks. San Francisco has seen a higher frequency than normal of overcast skies at 11 a.m. compared to average this summer. The cloud cover from the enhanced marine layer has allowed temperatures to trend cooler during the day. Californians have nicknamed the weather patterns as 'May Gray,' 'June Gloom,' and 'No-Sky July.' 'June gloom is so named as June can be one of the months that tends to have more persistent marine clouds than any other month,' weather expert Ken Clark with AccuWeather said. This summer season has seen a dense marine layer, resulting in colder temperatures and cloudy conditions for Californians along the coast. Greg Porter, the senior meteorologist with the San Francisco Chronicle, noted that Tuesday was the second day in a row when the entire Bay Area stayed under 80 degrees Fahrenheit. 'This cool, muted July follows an equally subdued June, driven by a combination of local ocean conditions and large-scale atmospheric patterns,' Porter said. 'Along the coast, colder than normal sea surface temperatures sharpen the marine layer, leading to thicker cloud cover, slower clearing and dampened daytime highs, even across the typically hot inland locations.' Porter predicted the gloomy conditions are here to stay until August. The forecast for parts of southern California remains chillier, with parts of San Francisco experiencing highs in the low to mid-60s. Meanwhile, those who live farther inland can potentially see drastic differences in temperatures. 'It's not uncommon to have it cloudy and in the 60s at the beaches while it's in the 80s or even 90s only 10-20 miles inland,' Clark explained. Another reason for the persistent haze off the golden coast is a pattern called the jet stream, which are narrow winds high up in the atmosphere. Porter explained that the jet stream has fallen into a semi-stationary rhythm, continuously holding over the same regions. The Earth has four primary jet streams that move weather systems from west to east. However, when a jet stream remains stationary, weather can stay relatively stagnant. 'California has been on the eastern flank of one such ridge, locked into a cool, cloudy pattern that persisted through June and July and now looks to continue into early August,' Porter said. 'Elsewhere, the same jet stream setup has delivered much more active weather from the grueling heat in Europe and Asia to the deadly flash floods across parts of the US.' The meteorologist predicted that this pattern is likely to continue through the summer, so those thinking of planning a beach vacation to the California coast may want to reconsider going west. As California experiences cooler and cloudier temperatures, other parts of the country are seeing extreme weather. Texas experienced deadly flash floods at the start of the month, killing over 137 people, while the Tri-State area reached over 100 degrees Fahrenheit in June.

Health officials urge Americans not to drink alcohol in 18 states: 'Could lead to permanent disability'
Health officials urge Americans not to drink alcohol in 18 states: 'Could lead to permanent disability' Health officials have warned people living in the south and Midwest to steer clear of alcohol this week due to 'extremely dangerous heat conditions.' The National Weather Service (NWS) issued a statement this week about severe heatwaves in 18 states, where temperatures could reach 100 degrees Fahrenheit (38 degrees Celsius) in the coming days. The temperatures are part of a 'heat dome' enveloping the US, which occurs when the atmosphere traps hot air over certain areas like a lid on a pot. The NWS warned alcoholic beverages act as diuretics, meaning they tell the body to produce and pass more urine. Increased urination causes the body to lose fluids, and if those fluids can't be replaced, the body becomes dehydrated. Without enough fluids, blood volume in the body diminishes, damaging the kidneys, heart, brain and other vital organs. High temperatures mixed with dehydration can lead to heat stroke, which the CDC warns could cause 'permanent disability.' Coffee and sodas have the same mechanism, so health authorities recommend opting for water or sports drinks instead. NWS also suggested limiting outdoor activities, opting for water instead of alcohol or sodas and wearing light clothing. The National Weather Service warned not to drink alcohol in extreme heat (stock image) The warning comes as heat-related deaths in the US have doubled in the past 25 years and could even triple in the next 50 due to gradually increasing temperatures. Around 1,200 Americans die from heat-related causes every year, though officials note the actual number could be 10-fold higher due to underreporting. As of Monday, extreme heat warnings, which the NWS issues when 'extremely dangerous heat conditions are expected or occurring,' were put in place for parts of Kansas, Oklahoma, Arkansas, Missouri, Mississippi, Tennessee, Kentucky and Illinois. The agency said heat index values, which measure how hot it feels to the human body when taking both temperature and humidity into account, were expected to surpass 100 degrees in these areas. Parts of Mississippi were even expected 115-degree heat. Less severe 'heat advisories' were issued this week for South Dakota, Nebraska, Texas, Iowa, Louisiana, Alabama, Florida, Georgia, North Carolina and South Carolina. Diuretic drinks like alcohol tell the kidneys to release more water and produce more urine, which helps the body get rid of excess fluid. But in hot temperatures, the body is already losing fluid due to sweating, so diuretics could drain the body of fluids faster than they can be replaced. In response, blood volume decreases, which means not enough of it can flow to vital organs. This makes sweating, which cools the body down, less effective and makes the body's internal temperature increase. This leads to heat stroke, which causes nausea, vomiting, a rapid pulse, loss of consciousness and organ failure. NWS said on X: 'Dangerous heat in the southeast on Saturday will begin to build into the mid-Mississippi Valley and Midwest by early in the upcoming workweek. 'Major and Extreme HeatRisk are designated for conditions not only to vulnerable populations but also anyone without effective cooling and/or adequate hydration.' The agency has also warned earlier this summer against eating meals high in protein during a heat advisory. Compared to carbohydrates and fats, protein takes more energy to digest into amino acid, meaning the body burns more calories. This generates heat. Body temperature increases as a result, a process called diet-induced thermogenesis (DIT). This could explain why eating protein-rich foods might cause 'meat sweats.' NWS suggested skipping chicken and steak and instead opting for foods with high water content like watermelon, berries, melons and cucumbers.
